Yeah! Did/do you work on it? The original publications were good timing; I was working as a consultant on an FPGA-based ML accelerator at the time the original stuff was talked about, and I really enjoyed reading everything I could about Brainwave! Really neat project from both a system design perspective (e.g. heterogeneous compiler) to the choice of using and interconnecting FPGAs and integrating the network/software/ML stack (IIRC, there was a good paper on the overlay network they used to make those custom functions available on the global network fabric.)

I'm guessing at this point the ASICs make a lot more economic sense, though. :)

Sorta! Tangentially on the data science side - Brainwave pre-dates me being at MS though. It's a really cool project and I'm glad someone else also thinks so :) I was enamored with FPGAs from undergrad, one of the professors I did research with was a consultant on the original Catapult project, I thought it was the coolest idea. It was pretty awesome to be able to come full circle a fews years later.
